Answer:
E=-1.51 eV.
Explanation:
The nth level energy of a hydrogen atom is defined by the formula,
Given in the question, the hydrogen atom is in the 3p state.
Then energy of n=3 state is,
Therefore, energy of the hydrogen atom in the 3p state is -1.51 eV.
Now, the value of L can be calculated as,
For 3p state, l=1
Therefore, the value of L of a hydrogen atom in 3p state is .

Iron transition metal
Potassium Alkaline metal
Strontium Alkaline earth metal
Platinum transition metal
The periodic table arranges elements based on their atomic numbers into periods and groups. Atomic number is the number of protons an atom contains.
On the periodic table:
Group IA is called Alkaline metal
Group IIA is the Alkaline earth metals
Group IIIA Boron family elements
Group VIIA Halogens
Group O Noble gases or inert gases.
Group IIIB to IIB Transition elements.
Running a check of the given elements on the periodic table will confirm answer.

A heat pump is a device that puts out heat. It involves pumping a lever over and over to get energy so it can work.
Answer:
increase by 8 percent
Explanation:
<em>Price elasticity of supply of a product is the degree of responsiveness of supply of that product to a change in price.</em> Simply put:
Price Elasticity of supply = change in quantity supply/ change in price.
In this case, price elasticity of supply of gasoline = 0.4
Percentage price increase = 20 percent.
Hence,
0.4 = change in supply/20
Change in supply = 20 x 0.4 = 8 percent
<em>Therefore, the quantity supply of gasoline will increase by 8 percent</em>
